I FEEL CHEATED, NOT INFORMED CORRECTLY AND OVERCHARGED

I have been a regular at Coffee Time Princess Crossing for years. I will however never go there again and will tell all my friends and family not to. This is the second incident, I let the first one go and gave them a second chance and then this happened: My mom and I each ordered a WHOLE slice of cake, one Lemon Merengue and one Baked Caramel Cheesecake. The waitress came to inform us they did not have Lemon Merengue in stock, so we asked for two WHOLE pieces of cheesecake. Whilst the waitress was away I noticed there was only one single whole slice of cheesecake in the display, but thought maybe they have another cheesecake in the kitchen. The waitress proceeded to serve us the single piece of whole cheesecake cut into two slivers she called halves on each of two plates, she placed one down in front of my mom and the other in front of me. I told her I knew this was one slice cut in two, so I was only prepared to pay for one slice of cheesecake. She simply looked at me and walked away. Only to present me with a bill containing an inflated price for each of the two "halves", which works out to more than R20 more than if only one of us had ordered that same ONE piece of cheesecake!! Only for the manageress to tell me she doesn't want me to feel cheated as a customer! I told her I DO feel cheated, but they still simply WOULD NOT correct the price to one single piece of cheesecake. It seems we were penalized heavily for their lack of stock and for dirtying a knife in the kitchen to cut a single piece of cake in two, which I would've done myself with pleasure if the waitress had given us the single piece on one plate. She never informed us that there was only one piece of cheesecake and never asked us if we wanted a different piece of cake instead, after finding that the cheesecake stock was also insufficient. She never informed us of the price for two so-called halves either. Simply presented the one piece on two plates and charged us heavily for it AFTER we had unfortunately eaten it. Very unfair.
